The Kimble/Kontes KIMAX Test Tubes, Reusable, Borosilicate Glass, Kimble Chase 45042 18150: A Review After Real Use
The Kimble/Kontes KIMAX Test Tubes, Reusable, Borosilicate Glass, Kimble Chase 45042 18150 are laboratory staples, but their utility extends far beyond the sterile environment of a research facility. These aren’t your flimsy, single-use plastic tubes; these are robust, reusable vessels made by Kimble/Kontes from high-quality borosilicate glass. With a size of 18 x 150 mm and a 28 mL volume, they promise reliability for both critical experiments and, surprisingly, some very specific outdoor applications.
I’ve spent years improvising field solutions, from makeshift water purification systems to improvised medication storage. The need for a durable, chemically inert, and heat-resistant container led me down the rabbit hole of laboratory glassware. I needed something far more reliable than plastic for specific sterilization and containment needs in the field.
My first encounter was a box fresh from the supplier. The immediate impression was one of quality; each tube felt solid, uniformly thick, and clearly well-made. The Kimble/Kontes KIMAX Test Tubes, Reusable, Borosilicate Glass, Kimble Chase 45042 18150 inspired confidence.
Compared to cheap, generic test tubes found online, the Kimble/Kontes tubes were noticeably superior. The difference in glass clarity and wall thickness was immediately apparent. I had also considered using thick-walled centrifuge tubes, but their conical shape limited their utility for certain procedures I had in mind.
My initial reaction was excitement mixed with a healthy dose of skepticism. Could these laboratory-grade test tubes truly hold up in the rugged outdoors? The prospect of reliable sterilization in the field was a game-changer, but I knew they’d need to prove their mettle.
Real-World Testing: Putting Kimble/Kontes KIMAX Test Tubes, Reusable, Borosilicate Glass, Kimble Chase 45042 18150 to the Test
First Use Experience
My first real-world test took place during a remote survival skills course in the Arizona desert. I used the Kimble/Kontes KIMAX Test Tubes, Reusable, Borosilicate Glass, Kimble Chase 45042 18150 to sterilize water samples using direct sunlight (solarization). It’s a basic technique, but critical for avoiding waterborne illnesses.
The tubes performed admirably, resisting the intense heat without cracking or clouding. The uniform glass thickness allowed even heating. The clarity of the glass let me confirm that the samples were free of debris.
Using the tubes was surprisingly straightforward. However, I quickly realized the need for a protective carrying case to prevent breakage during transport. Post-solarization, I needed insulated gloves to safely handle the hot tubes.
No major issues arose during this initial use. I was pleasantly surprised by the tubes’ resilience and their effectiveness in a critical survival scenario.
